Hello Vanessa,

DMSO is compatible with plastics like PETE, HDPE, LDPE ,PTFE and PP, however it is not compatible with other plastics such as , PVC, PS and poly carbonate due to its reactivity .Also reacts with many acid chlorides,

DMSO is highly hygrocopic and stored in air tight bottles.Since it is highly hygroscopic it always proffered to use fresh solvents ..

Here is useful links to DMSO data sheet

Hi Vanessa,

I would always choose glass to avoid possible migration of plastic and stabilisers to your solvents.

Cheers

Ludovic Dumont

I'm agree with answers proposed for the preservation of DMSO.

Moreover, please see following topics for :

i) the light sensitivity, https://www.researchgate.net/post/Is_DMSO_light_sensitive

ii) the way of storing DMSO in research lab, https://www.researchgate.net/post/What_is_the_best_right_way_of_storing_DMSO_in_research_lab

Hoping that this complement reply will be useful,

a bit late but thank yu al very much for your answer!

Narges Mahmoodi

It depends to the material of your falcon. It is written on the bag of your falcon.

The compatibility of DMSO with various materials is

listed below:

• Compatible: LDPE, HDPE, polypropylene, PPCO

(polypropylene copolymer), polymethylpentene,

nylon, teflon FEP

• Moderately compatible: polystyrene,

ECTFE/ETFE

• Incompatible: polysulfone, flexible and rigid PVC

tubing, polycarbonate

I dont know how I missed your answer, but thanks a lot NArges !

I am also confused about this problem, when I use DMSO dissolute coumarin 7, and then store in plastic tube, use fulorescence imaging, but i can not get right shape of it tube

Mingchuan Yu

We can simply aliquote DMSO into 1.5 ml or 2 ml eppendorf tube and keep in 4C. It does not matter. Since the tube is small, it will not take much time to thaw again. It is safe. I have been using such way for 15 years. No issue at all.
